IT Outsourcing for Companies: Models, Costs and How to Choose a Provider

By the ITDS Poland team · Warsaw

Your company needs more people in IT, or skills nobody on the team has. Hiring a senior takes months, and the project won't wait. That is usually when someone says "IT outsourcing". The trouble is that the term covers several very different services, from a helpdesk to a team of developers working only for you.

This guide gives an honest view of the whole market. It explains what IT outsourcing for companies means, the main models, when it makes sense to bring in external specialists, what it costs and how to choose a provider. ITDS specialises in one of these models, providing IT specialists and teams, including nearshore teams from Poland and Portugal for companies across Europe and the US.

What is IT outsourcing for companies?

IT outsourcing means handing part of your technology work to an external company. That might be supporting staff computers, running servers, developing software or providing specific specialists to join your team.

Companies outsource for three main reasons. The first is access to skills they can't hire quickly. The second is speed, because a good provider can start in weeks rather than months. The third is flexibility: it is easier to grow or shrink a team as needs change. Savings can come too, but they are rarely the main reason. They are the proof that the model works, not the pitch.

The talent shortage is real across Europe. According to Eurostat, more than half of EU companies that tried to hire ICT specialists in 2023 struggled to fill those roles.

IT outsourcing for companies: five models

These models are often confused, and each one solves a different problem. Before you talk to a provider, decide which one you need.

Helpdesk and infrastructure management are ongoing services, usually paid as a monthly fee. The other three models concern building software and differ in who directs the work and who carries the risk.

Outsourcing IT specialists: when it is the best choice

If your company has its own IT team but lacks people or specific skills, outsourcing specialists is usually the fastest and most flexible answer. The provider finds, vets and employs the expert, who then works in your team, with your tools and under your lead.

How it works in practice

1. You describe the role: technologies, seniority, way of working and how long the project will run.
2. The provider searches for candidates and checks their technical and language skills.
3. You interview a short list of the best people and choose.
4. The specialist joins your team. The provider handles the contract, invoicing and any replacement.

When it makes sense

• You have a technical lead who can direct the new person's work.
• You need a specific skill faster than permanent hiring allows.
• Demand changes over time, for example during a large rollout or migration.
• You are looking for a rare profile, such as a data, cloud or security specialist with financial services experience.

What to watch out for

Outsourcing specialists won't work if nobody in your company has time to lead them. In that case, a dedicated team with its own lead is a better fit. It also pays to treat external specialists as part of the team: the same tools, the same meetings, the same access to knowledge.

That is how ITDS works. Roughly one in five candidates passes our vetting, and on average it takes about 20 days from starting a search to a specialist working in the client's team. We recruit in Poland and Portugal, most often for financial services companies.

How much does IT outsourcing cost?

The cost depends mainly on the model. Helpdesk and infrastructure management are usually billed as a monthly fee based on the number of users or systems. Specialists and dedicated teams are usually billed at an hourly or daily rate per person. A fixed-price project has a price agreed up front for the whole scope.

For specialists, the rate depends on the technology, seniority and contract type. For example, according to the ITDS IT Talent Trends 2026 report, senior B2B rates in data and AI in Poland are usually around PLN 140–170 net per hour for data scientists and around PLN 180–220 per hour for AI and ML engineers. A provider's rate also covers recruitment, the contract, replacement and account management. Treat these figures as approximate and confirm current rates before you budget.

When you compare offers, look at total cost, not just the rate. Time to start, candidate quality, turnover risk and who pays for a replacement all matter. A lower rate from a provider that needs three months to find someone often costs more than a higher one from a provider that delivers in three weeks.

How to choose a provider: IT outsourcing for companies step by step

Ask every provider the same questions. Good ones answer them without hesitation.

1. Which model do you specialise in? A helpdesk company is rarely the best at providing developers, and the other way round.
2. How do you vet candidates, and who does it? Ask about technical interviews and language tests.
3. How long does it take to provide a specialist? Ask for real figures from recent months, not promises.
4. What happens if someone leaves? Check the replacement terms and the notice period.
5. Who have you worked with? Ask for references in your industry.
6. What do the contract and billing look like? Rates, minimum term and how the contract ends.
7. How do you protect data? Data processing agreement, access controls and security certifications.

GDPR and security in IT outsourcing

If external specialists will have access to personal data, you need a data processing agreement. It sets out how the provider may use the data, how it protects it and what happens to it when the work ends. When specialists work inside the EU, for example in Poland or Portugal, you avoid the extra formalities of transferring data outside the EU.

Financial companies must also meet requirements for managing ICT supplier risk, including the EU's DORA regulation. This is general information, so discuss the contract details with your lawyer or data protection officer.
